How would you like to use vllm

I I tried deploying qwen2-vl-7b using vllm with commands:

VLLM_WORKER_MULTIPROC_METHOD=spawn CUDA_VISIBLE_DEVICES=4,5,6,7 nohup python -m vllm.entrypoints.openai.api_server --served-model-name Qwen2-VL-7B-Instruct --model MY_MODEL_PATH --pipeline-parallel-size 4  --gpu-memory-utilization 0.8 --limit-mm-per-prompt image=4 --port 11435 --disable-custom-all-reduce >> nohup_logs/vllm.log 2>&1 &

Please forgive me for the complex parameter settings, as I conducted numerous searches and attempts to successfully deploy and added many parameters to ensure it works.

And my device configuration is as follows:

Here is the exception I found：

During the inference, I found that if the prompt is short (or there are few images passed in), the model runs normally in most cases. However, when the prompt is long (or there are many images passed in), the VLLM program will get stuck or generate errors and output the following error message:

The subprocesses of vllm also do not automatically terminate and continue to occupy the GPU unless you manually kill them.

I have tried various measures, including but not limited to: changing the -tp parameter to -pp, adding the --disable-custom-all-reduce parameter, reducing the --gpu-memory-utilization, and upgrading the vllm version, but the situation has not improved yet.

All I hoped is someone can help me to ensure that qwen2-vl-7b can perform inference stably within its context length range(32768, including image tokens) without experiencing llm_engine crashes or similar issues. 🐧

I think this is potentially caused by the long processing time, as documented in #9238. You can try preprocessing the images to be smaller before passing them to vLLM and/or set max_pixels via --mm-processor-kwargs.

Thanks for the clue.

In order to reduce the processing time, I installed pillow-simd from https://github.com/uploadcare/pillow-simd, which is a faster implementation for PIL using AVX-2 accelation.

After using pillow-simd, this issue disappeared.
